LIMITED WARRANTY & LIM ITATION OF LIABILITY

Each Fluke 20, 70, 80, 170 and 180 Series DMM will be free from defects in material and workmanship for its lifetime. As used herein, “lifetime” is defined as seven years after Fluke discontinues manufacturing the product, but the warranty period shall be at least ten years from the date of purchase. This warranty does not cover fuses, disposable batteries, damage from neglect, misuse, contamination, alteration, accident or abnormal conditions of operation or handling, including failures caused by use outside of the product’s specifications, or normal wear and tear of mechanical components. This warranty covers the original purchaser only and is not transferable. For ten years from the date of purchase, this warranty also covers the LCD. Thereafter, for the lifetime of the DMM, Fluke will replace the LCD for a fee based on then current component acquisition costs. To establish original ownership and prove date of purchase, please complete and return the registration card accompanying the product, or register your product on http://www.fluke.com. Fluke will, at its option, repair at no charge, replace or refund the purchase price of a defective product purchased through a Fluke authorized sales outlet and at the applicable international price. Fluke reserves the right to charge for importation costs of repair/replacement parts if the product purchased in one country is sent for repair elsewhere. If the product is defective, contact your nearest Fluke authorized service center to obtain return authorization information, then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Fluke will pay return transportation for product repaired or replaced in-warranty. Before making any non-warranty repair, Fluke will estimate cost and obtain authorization, then invoice you for repair and return transportation. THIS WARRANTY IS YOUR ONLY REMEDY. NO OTHER WARRANTIES, SUCH AS FITNESS FOR A PARTICULAR PURPOSE, ARE EXPRESSED OR IMPLIED. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY. AUTHORIZED RESELLERS ARE NOT AUTH ORIZED TO EXTEND ANY DIFFERENT WARRANT Y ON FLUKE’S BEHALF. Since some states do not allow the exclusion or limitation of an implied warranty or of incidental or consequential damages, this limitation of liability may not apply to you. If any provision of this warranty is held invalid or unenforceable by a court or other decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

Multimeter Safety

Read this information before using the meter. This meter complies with EN 61010-1:1993, ANSI/ISA S82.01-1994 and CAN/CSR C22.2 No. 1010.1-92 Overvoltage Category III. Use the meter only as specified in this Users Manual, otherwise the protection provided by the meter may be impaired.

• A Warning identifies conditions and actions that pose hazard(s) to the user.

• A Caution identifies conditions and actions that may damage the meter or the equipment under test.

W Warnings

To avoid possible electric shock or personal injury:

• Inspect the meter before using it. Check for cracks, missing plastic, or other possible damage to the case. Make sure that the insulation surrounding the connectors is intact.

• Inspect the test leads for damaged insulation, exposed metal, and continuity. Replace damaged test leads before using the meter.

• Do not use the meter if it operates

abnormally. Protection may be impaired. When in doubt, have the meter serviced.

• Do not operate the meter around

explosive gas, vapor or dust.

• Do not apply more than the rated voltage

(1000 V) between terminals or between any terminal and earth ground. The rated voltage is marked on the meter.

• Before each use, verify the meter’s

operation by measuring a known voltage.

• Use only specified replacement parts.

• Use caution when working above 30 V ac

rms, 42 V ac peak, or 60 V dc. Such voltages pose a shock hazard.

• When using the probes, always place

fingers behind the probe finger guards.

• Connect the common test lead before

connecting the live test lead. When disconnecting test leads, disconnect the live test lead first.

• Make sure the battery door is secured

before operating the meter.

Users Manual

• Remove test leads from the meter before

opening the battery door.

• Use only a properly installed, single 9 V

battery to power the meter.

• Follow all equipment safety procedures.

• Check the meter’s fuses (see “Testing the

Fuses”) before measuring current.

• Never touch the probe to a voltage

source when the test leads are plugged into the 10 A or 40 mA input jacks.

• The use of makeshift fuses and the short-

circuiting of fuse holders is prohibited.

• To avoid false readings, which could lead

to possible electric shock or personal injury, replace the battery as soon as the battery indicator (M) appears.

• The meter is waterproof to a depth of 1

meter. Remove all surface water from the product including water around, within and under the rotary knob, input receptacles and buttons prior to connecting any voltages to the input.

International symbols used on the meter and in this manual are explained in Table 1.
